Working remotely with minimal supervision from a Lead Designer or Engineer, this role interprets engineering design input, develops constructible 3D models and drawings, and coordinates across disciplines to ensure designs are accurate, code-compliant, and field-ready. This position requires proven design experience in industrial or petrochemical environments, strong 3D modeling proficiency, and the judgment to work independently in a remote setting while maintaining close coordination with project teams.

  • Prepares detailed design deliverables for engineer review and approval

  • Assumes responsibility for the technical accuracy and constructability of finished designs

  • Performs interference and clash detection/resolution across disciplines within the 3D model

  • Develops and maintains line lists, valve lists, and specialty item lists in support of design packages

  • Coordinates with stress engineers on critical line routing, expansion loop design, and pipe support/anchor placement

  • Supports tie-in design for brownfield and turnaround work, including isolation planning for live/operating units

  • Generates material take-offs (MTOs) to support project cost estimates

  • Facilitates or participates in remote model reviews and interdepartmental design coordination meetings

  • Communicates project schedules, design status, and variances to the project team and leadership

  • Supports construction through RFI response, redline incorporation, and field walkdown coordination as needed

Required Qualifications
  • Technical training in drafting/design from an accredited program (Associate's degree preferred) or equivalent industry experience

  • Minimum 5 years of facilities/piping design experience in industrial, petrochemical, oil & gas, or related heavy-industrial settings

  • Proficiency with AutoCAD and 3D modeling software (CADWorx, AutoPLANT, or S3D preferred)

  • Working knowledge of engineering design principles, plant layout, and constructability practice

  • Experience with 3D model review and clash detection tools (Navisworks or equivalent)

  • Familiarity with laser scan software (e.g., ReCap, LFM) a plus

  • Knowledge of P&ID interpretation, redlines, and ISO sketching

  • Understanding of pipe stress fundamentals and pipe support/anchor design principles

  • Bluebeam Revu or equivalent markup/review software experience preferred

  • Demonstrated ability to work independently in a remote environment while maintaining strong cross-discipline communication

  • Proficient in MS Word, Excel, Outlook, and PowerPoint

  • Strong organizational skills with the ability to manage time, priorities, and resources across multiple concurrent design packages

  • Experience with a consulting engineering firm or EPC environment preferred
